To 11]/ 11"/10711, ff 71mg/ collar/WIL.'

Be it known that I, HARRY KING, a citizen of the United States of America, residing at lVashington, in the Districtof Columbia, have invented certain new and useful Improvements in Coke-Fullers, of which the following is a specification.

This invention relates to a coke-puller designed to be operated by mechanical means 1o for pulling coke from coke-ovens, and it is particularlyY adapted for discharging coke from beehive coke-ovens. ln the manufacture of metallurgical coke the oven known as the beehive oven, so cz lled because of its 15 dome-shaped form7 has been generally adopted, being' found to give the best results. In the burning' of the coal the coke is produced in a caked mass having' a vertical stratification, and it is desirable to avoid as much as possible breakage of the sticks and lumps extracted from the oven.

The invention relates more especially to a coke-puller of a type somewhat analogous to the ordinary duck-bill coke-puller.

The object of the invention is to provide simple and eti'ective mechanical means for operating such a coke-puller in a manner similar to the hand method of manipulating' cokepullers of this types-that is, to impart to it a vertical reciprocatory motion for clawing the coke within the oven, a lateral swing to engage coke at the sides of the oven, an axial motion to turn it upon its side to adapt it to act as a scraper for drawing out the coke, a

longitudinal reciprocatory motion for etl'ecting the withdrawal thereof from the oven, and any desired compound movement as the resultant of any two or more of such motions.

Another object of the invention is to render the blade adjustable into an approximately horizontal position to enable it to pass under the bed of coke along the bottom of the oven and act as an underworking wedge-like lifter to loosen the coke j )reparatory tothe withdrawal thereof from the oven.

Figure I of the accompanying'drawings represents a side elevation, partly in section, of one embodiment of this mechanical coke-puller mounted on a traveling' carriage and operating within the coke-oven as a scraper for withdrawing the coke, the dotted lines indicating' the position of the coke-puller when elevated for clawing the coke from the top of the caked mass thereof. Fig. 2 represents a rear elevation of the coke-puller and its supporting-car- 5 5 riage, showing the means for axially oscillating and adjusting the cokepuller rod for changing the angle of the coke-puller blade, parts being' broken out. Fig. 3 represents, on an enlarged scale, a longitudinal vertical section of the rear end of the coke-puller rod and its immediate support. Fig'. 4 represents a transverse section of the coke-puller bar on line 4 a of Fig. I, showing a rear elevation of the coke-puller blade. Fig'. 5 represents a 65 longitudinal section of the front end of the coke-puller, showing the connection of the blade thereof with its supporting and actuating' rods.

Similar reference characters indicate corre-4 70 sponding parts in all the figures.

This coke-puller comprises a coke-puller bar 10, a coke-puller blade 20, a blade-adjusting' slide-bar 30, a link 4l), connecting the blade with said slide-bar, and means for supporting and actuating' said bars.

The coke-puller blade 20 has a pivotal connection with the bar l() by any suitable means to enable it to be adjusted 'from a position at right angles, or substantially so, to said bar, 8O where it is adapted for use as a claw or scraper, to a position approxim'ately in line with said bar, where it is adapted to a wedge-like action for lifting' and loosening'4 coke. The hollow bar l0 is provided at its outer end with a lug 85 l1 and near said end with a slot l2. rl`he cokepuller blade Q0 is provided on its inner face near its upper end with a bent lug 2l and preferably with a corresponding bent lug Q2, between which the lug II of the hollow bar I0 projects, and a pivot-pin 23 passes through said blade lugs near their inner ends and through said intermediate bar-lug. The sliden bar 30 is provided at its outer end with a lug 3l, which projects through the slot l2 in the 95 hollow har 10, and the link 0 is pivoted at blade.

its front end to the outer ends of theblade-lugs outside the pivot thereof.

The coke-puller bar 10 is mounted in such a manner as to permit a vertical oscillation thereof to eect a clawing operation of the Any suitable support may be provided for this purpose. The drawings show an oscillating coke-puller socket 50, which is provided with trunnions 51 and 52, journaled in bearings of standards 61 and 62, mounted on a coke-puller carriage 60. This socket is preferably provided at its rear end with a counterweight 54, operating to counterbalance, or partly so, the weight of the coke-puller projecting from said socket. This counterweight is preferably provided with a notched rim 55, adapted to constitute the fixed part of a leverlock, as hereinafter explained. The cokepuller bar 10 is supported in this socket and is provided with a shoulder 13 in front of said socket and with a `grooved collar 14 at its inner end behind said socket. The coke-puller bar is provided near its rear end with an angular socket 15 and beyond said socket with a longitudinal slot 16.

Means are provided for oscillating the cokepuller socket 50 to impart the clawing motion to the coke-puller. The means shown for this purpose are preferably within easy reach of the operator and comprise a yoke 70, disposed between the standards 61 and 62 and pivoted by trunnions 71 and 72 in said standards in front of the bearings for the trunnions of the oscillating socket 50. This yoke is provided with a crank-arm 7 3, which extends approximately parallel with the coke-puller bar 10 and is adapted to engage the socket to oscillate it. For this purpose the crank-arm may be provided at its outer end with an inwardlyprojecting crank-pin 7 4, which engages a longitudinal slot 53 in the front portion of the oscillating coke-puller socket 50, as shown in dotted lines in Fig. 3, or the pin and slot may be reversed. A lever 75, herein called the clawing lever, is secured to one of the trunnions of the yoke 70, and the oscillation of this lever causes the crank-arm to lift and lower the outer end of the coke--puller socket 50, thereby swinging the coke-puller bar l() in a vertical plane and imparting a clawing action to the coke-puller blade 20 within the oven.

Means are provided for axially oscillating the coke-puller bar 10 to adjust the blade or scraper 2O at different angles as desired. Any suitable means may be used for this purpose. The means shown comprise a lever 80,

disposed at the rear end of said coke-puller bar between the collar 14 thereon and the rear end of the coke-puller socket 50, preferably V adjacent to the counterweight 54 on the latter. This lever is provided with a spring-actuated bolt 81, which is adapted to engage the notches in the rim 55 of said counterweight and with a finger-lever 82 at its outer end connected with said bolt and adapted to actuate the latter. A swing of the lever 8O toward the right or left will cause the bar 10 to turn on its axis and the blade 2O to assume a position at any desired angle, either horizontal or inclined, and the lever-lock will operate to fix the parts in such position. The lever'SO preferably projects from the axis of the bar in a direction opposite to the lateral projection of the blade.

Means are provided for adjusting the cokepuller blade from a position at substantially right angles to the bar, where it acts as a claw or scraper, to a position substantially in line with the coke-puller bar to adapt it to slide along the bottom of the oven and serve as a wedge for lifting and loosening the caked coke within the oven. The means shown for this purpose will now be described. The slidebar 3() is preferably disposed within the cokepuller bar 10. the latter being made hollow to receive it. This slide-bar is provided at its front end with a laterally-projecting lug 31,

which extends through the slot 12 in the bar 10. The link 40 is connected at its rear end with the lug 31 and at its front end to the outer end of the shanks or lugs 21 and 22 of the blade 20. The slide-bar 30 may be provided near its rear end with an angular enlargement 32, which fits into the angular socket 15 of the bar 10, whereby the slide-bar is made to turn in unison with the bar 1() when the latter is turned on its axis. The bar 3() is also provided beyond the angular enlargement 32 with a rib 33, adapted to slide in the slot 16 of the bar 10 and provided with a segmental screw-thread 34. An enlarged screw-nut 90, preferably having an elongated thickened body adapted to serve as a supplemental counterweight for the coke-puller, has a plain socket 91 at its front end, which is adapted to fit over the grooved collar 14 of the bar 10. This socket is provided with a fasteningscrew 92, which projects through the wall of the socket and takes into the groove of the collar and holds the nut in connection with the bar, but permits it to turn freely on the latter. This nut is provided with interior screw-threads 94 beyond the end of the bar 10, which engage the segmental screw-threads 34 of the slide-bar 30. This nut is preferably provided with a hand-wheel rim 93, by which it is turned in either direction at the will of the operator. By turning the nut toward the right the slide-bar 30 is thrust outward, and the blade 20 is swung on its pivot, its pointed end moving outward approximately into line with the bar and its body assuming a wedge-like position, as shown in Fig. 5. The turning of the nut in the opposite direction will cause the blade to assume a position substantially at right angles to the bar, as shown in Fig. 1.

An indicator 35 is preferably attached to oven to oven and made to travel toward and l from the coke-oven by any suitable means for thrusting the coke-puller into the oven and withdrawing it therefrom to pull out the coke.

The lugs or shanks 2l and of the blade l 2O are preferably provided with frictionrolls i and -t to facilitate the movement of the coke-puller along' the bottom of the oven when used as a coke-loosener. These antifriction-rolls may be placed on the front pivoti pin of' the link Veff).

ln the use of this apparatus the machinecar or other traveling or movable support for the coke-puller carriage is run into position in front of an oven from which the coke is to be drawn. The drawing' operation is preferably performed in two steps, the first step involving the loosening of the eaked mass of coke within the oven preparatory to the withdrawal thereof and the second step consisting in pulling out the loosened coke. The loosening' of the entire mass may be first effected or the loosening and drawing may be performed in alternation. Preparatory to the loosening operation the operator turns the nut 9o toward the right. thereby thrusting the slide-bar outward and swinging' the blade 2l) approximately in line with its supporting'- bar 1l) into position to have a wedge-like aetion upon the coke. as shown in Fig. 5. Then the carriage is made to move toward the oven, the coke-puller bar 10 being' held in horizontal or approximately horizontal position. and the blade Q0 rides in along' the bottom of the oven and having a wedge-like aetion. operates to lift the coke under which it passes on its instroke and separates a strip of coke equal to the width of the blade at its widest part from the caked mass of coke within the oven. Then the coke-puller carriage iscaused to move away from the oven and the coke-puller withdrawn therefrom. Before the outstroke is begun the coke-puller bar 1t) may be turned at ninety degrees on its axis and the blade 2O may be swung into transverse or scraping position, as shown in Figs. l, 2, and sf. by means of the nut and slide-rod to adapt it to act as a scraper and pull out loosened coke from the oven on the outstroke. The coke-puller bar 10 may also be turned a further ninety degrees on its axis before the outstroke, so as to cause the blade to project upward to better engage the coke on the outstroke. In the withdrawing or discharging operation the blade 20 is adjusted to a position at right angles to the bar 10, in which it is best adapted to serve as a claw or scraper. As the coke-puller carriage moves toward the oven the operator swings the clawing-lever T5 backward and lifts the cokepuller into the dotted-line position of Fig. l. so that as it enters the oven it passes over the top of the mass of coke therein. After the coke-puller enters the oven a sufficient distance to make the proper stroke the operator swings the lever T5 backward and forward. thereby imparting a vertically-oscillating motion to the blade and causing it to claw or break through the top of the coke within the oven if it has not been already broken by a wedging action of the blade. rlhe blade Qt) may be adjusted to different angles laterally by the axial lever 8f), and the coke-puller lnay be swung laterally to opposite sides of the oven by a traverse of the suplmrting-car or by a s\\'iveling of the carriage-support on said car.
